LV Power Cable Production Line
What is an LV power cable production line? It prepares power-cable conductors, applies the specified insulation, assembles the cores and extrudes the outer sheath. Match the line to copper or aluminum, the conductor size and the insulation system; XLPE also requires an approved crosslinking route.

02 Cable definition
Define the LV Power Cable Before Selecting Equipment
This four-core illustration shows stranded copper conductors, separate insulation, fillers and an outer sheath. Confirm the approved construction before selecting conductor preparation, insulation, curing, cabling and sheathing equipment.
Known inputs and open confirmations
- Cable family
- Unarmoured, multi-core LV power cable

Conductor construction and cable core count are separate inputs.
For a stranded conductor, provide the wire count, wire diameter and nominal area, plus compaction or sector shape where applicable. Define the number of insulated cores separately. Conductor stranding takes place before insulation; core laying-up assembles the insulated cores.
03 Preliminary process route
Match the Route to the Cable Construction
This route covers the unarmoured, multi-core LV power cable reference. Choose the actual incoming material. The insulation system determines the extrusion setup and whether a separate crosslinking process is required.
Prepare wires if needed → Strand conductors → Insulate / complete specified curing and core checks → Lay up cores → Sheath → Cool, test and drum
Stranded, multi-core reference. Solid conductors bypass stranding. Confirm the XLPE curing schedule independently of the drawing order.
Typical process / not a fixed layout
XLPE decision point: select the compound and crosslinking method before approving the line. Moisture-curable systems need defined cure conditions and time; other systems can require different equipment. The inspection image is not a curing machine. Core acceptance, reel holding and the position of curing in the schedule must follow the material instructions and approved process. PVC insulation has no XLPE curing step.
Stage 02 / Before insulation / stranded design
Conductor Stranding
Form each bare conductor from its specified wires. Add compaction or shaping only where required by the conductor design.
- Input
- Approved individual wires and conductor layer construction
- Output
- One conductor of the required area, shape and resistance
- Equipment source
- Equipment category; manufacturer, range and responsibility in the confirmed proposal
- Confirm
- Strander type, wire count, lay, material, compaction tooling, conductor shape and reel mass; solid conductors bypass stranding
04 Equipment by required stage
Review the Equipment Categories for This Route
Review each machine’s actual function, then confirm its model and interfaces. These are 3D category references; not an automatic equipment configuration or a claim that one machine performs every downstream operation.
Existing 3D category illustration; range and complete equipment arrangement require review
01 / Equipment configuration
Wire Preparation
Prepare conductor wire to the required diameter and material condition. Use material-specific drawing and heat-treatment arrangements.
Material grade, incoming size, final wire size and condition; do not apply a copper annealing setup to aluminum without review
05 Manufacturing and integration
Keep Every Equipment Source and Responsibility Explicit
A coordinated production-line project does not mean one factory manufactures every machine. Each source and interface is defined in the approved proposal.
LV Power Cable, one coordinated project interface
Proposal-defined scope
Equipment source, contracting entity, integration boundary and service responsibility stay item-specific.
Manufactured by HONGKAI
Core-insulation and outer-sheathing equipment only where expressly identified as HONGKAI-manufactured in the confirmed proposal.
- Insulation and sheathing equipment identified in the proposal
- Mechanical assembly and electrical-control scope only as defined for each identified item
- Factory inspection or testing only where stated in the approved proposal
Integrated from Specialist Manufacturers
Material-specific wire preparation, conductor stranding or shaping, and core laying-up equipment. XLPE curing equipment and material handling are separately defined where required.
- Stranding and optional compaction or shaping matched to the conductor construction
- Drawing and material-specific heat treatment only where required
- Core laying-up equipment, tension control and project-specific interfaces
- Source and contractual boundary stated in the proposal
Supporting Equipment and Project Interfaces
Cooling and drying, approved XLPE curing arrangements where required, core and final tests, haul-off, intermediate reels and drum take-up or packing.
- Exact functions and equipment source remain project-specific
- Customer-side utilities and interface responsibilities
- Installation, commissioning and training scope if agreed

Select only the information you already have. This checklist records readiness for review and does not save or submit project data.
07 Quality checkpoints
Check the Conductor, Insulation and Finished Cable
Agree the inspection plan before equipment selection. These 3D references explain the checks; they are not factory photographs, customer cases or evidence of passed tests.
Conductor acceptanceConductor acceptance
Check the Bare Conductor
Confirm wire count, individual-wire diameter, lay, finished bare-conductor diameter and the specified conductor resistance.
Wire count inside one conductor is not the number of insulated cores. The 3D cable is a structure illustration, not a test sample.
Dimensional controlDimensional control
Measure Diameter; Verify the Wall
Measure insulated-core and finished-cable diameters. Verify core insulation and outer-sheath wall thickness separately by the approved measurement method.
A laser outside-diameter gauge alone cannot establish minimum wall thickness. The acceptance method and tolerances must be defined.
In-line electrical checkIn-line electrical check
Inspect the Dry Insulation
Cool and dry each insulated core before its specified spark test. Record faults and keep accepted core reels identifiable before cabling.
Core spark testing does not replace finished-cable electrical tests. Any sheath integrity test needs its own approved method and suitable electrical arrangement.
Finished-product releaseFinished-product release
Confirm the Sale-Ready Package
Verify conductor resistance, core identification, required electrical tests, cable dimensions and material tests. Include XLPE crosslinking acceptance where applicable, then confirm marking, length and drum packing.
The take-up image illustrates winding only. Drum load rating, test records and project acceptance require actual project data.
Keep illustration and evidence separate. Add actual trial records, sample measurements and project acceptance documents once available. No performance or certification is inferred from a render.

08 FAQ
Clarify the Route Before Requesting a Quote
These answers explain the decision path. They do not replace an approved cable design, technical solution, quotation or project proposal.
What does an LV power cable production line include?
The preliminary route includes conductor preparation if needed, conductor stranding for stranded designs, insulation, material-specific curing and core checks, core laying-up, outer sheathing, cooling, drum take-up and final tests. Purchased conductors or accepted insulated cores can remove completed upstream operations from the scope.
Can the line process both copper and aluminum?
That requires a material-specific review. Confirm conductor grade, area, wire construction, compaction or shape, tooling, tension, heat treatment and interfaces. The copper illustration does not establish aluminum capability or an approved range.
Is XLPE insulation complete after extrusion?
No. Crosslinkable insulation must achieve the required crosslinking through its defined process. Moisture-curable systems use moisture with specified conditions and time; other systems may require different equipment. Select the compound and obtain its processing instructions before defining curing equipment, holding areas and acceptance.
Can the same equipment make PVC and XLPE insulated cable?
Only after confirming the compound systems, screw and tooling, dosing and handling, processing window, cleaning and changeovers. PVC does not use the XLPE curing step. Do not assume an existing PVC extruder and cooling trough provide a complete XLPE process.
Are conductor stranding and core laying-up different?
Yes. Conductor stranding combines bare wires into one conductor before insulation. Core laying-up combines separately insulated cores into the cable assembly. They have different material, tension, lay and reel requirements.
Does this route include armour or every low-voltage cable design?
The illustration and route are unarmoured. Armour, screens, special fire-performance materials, sector-shaped cores and other constructions need their own review. Single-core designs bypass multi-core laying-up. Rated voltage and product compliance come from the approved design and test requirements.
What data is needed before selecting models and output?
Provide conductor material, area and shape, wire construction, number and sizes of cores, insulation and sheath grades and walls, curing method if applicable, bundle and cable dimensions, output mix, drum sizes and mass, utilities and the acceptance specification. No model or speed is confirmed by these illustrations.
How are supply, installation and acceptance responsibilities agreed?
The proposal identifies each equipment manufacturer, supply boundary, integration interface, utility requirement, commissioning or training service and acceptance responsibility. Factory and site tests use the agreed protocol and actual records.
